BURNISHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 493,033, dated March '7, 1893. Application filed July 11, 1892. Serial No. 439,588. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. KELLEY, of Rockford, in the county of Winnebago and State of Illinois, have invented a new Improvementin Burnishing-Machines; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon,'to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a view in front elevation of a machine constructed in accordance with my invention. Fig. 2, an end view thereof. Fig. 3, an enlarged broken view showing the eyebrow burnishers in their operative engagement with a knife. Fig. 4., isa broken plan View showing a pair of the pivotal spring actuated handle-edge burnishers. Fig. 5, a

broken plan view showing one of the springs employed for forcing the handle burnishers inward.

My invention relates to an improved machine for burnishing knives, the object being to produce a simple and convenient device,

having a large capacity for work.

With these ends in view, myinvention consists in a machine having certain details of construction and combinations of parts as will be hereinafter described, and pointed out in the claims.

The machine-frame A, to which my improvements are applied, may be of any apat their lower ends to adapt them to receive theends of the handlesof the knives D, which are arranged vertically, with their handles uppermost. Each of the said socketsisprovided. with an adjusting-screw C. The ex- .tremities of the blades of these knives are inserted into a grooved holder E, which is common to them all, and mounted in aichanneled cross-bar F, arranged horizontally,-'and supported at itsends by two parallel vertical rods F F, which are suspended from a horizontal shaft F located above the machineframe A, carrying at each end a cam F resting upon the upper edges of the box B, and slide B, and furnished at one end with a handle F by means of which it is rocked to cause the said cams to lift through the rods F F, or lower the cross -bar' F, and hence the grooved-holder E, receiving the ends of the knife-blades. The said cams F are virtually disks, each having a corresponding flat,

face. By turning the shaft F, by means of the handle F so as to present the flat faces of the said disks to the edges of the box'B, and slide B, the cross-bar F, is allowed to drop down a little, thus securing enough clearance room to the ends of the knife-blades to be inserted into the groove of the holder E, and the ends of the knife-handles to be aligned with the sockets C. After the knives have been thus arranged, the shaft F is rotated again so as to cause the cams to lift the rods F F, and hence thecross-bar F, whereby the knives are raised and their handles forced into firm engagement with the sockets G, be-

simultaneously burnished on both sides, and r on the edges of their handles, by a suitable arrangement of reciprocating burnishers. Thereto the machine is provided with two rows of handle-burnishers G G of which one I row is located on one side of the vertical series of knives, and the other row on the other side of the same. ranged directly opposite each other in the same horizontal plane, the burnishers of one row co-operating with the corresponding burnishers of the other row, so. that there is a These burnishers' are are.

pairof handle-burnishers for each knife. The machine is also provided with adouble I f blade-burnishers H and H, of whi h:

one row is located on one side of a series of knives, and the other row on the other side of the same. These bnrnishers are also located opposite each other in the same horizontal plane, and there are two for each knife, the corresponding bnrnishers of the two rows coperating in pairs.

The action of the handle and blade burnishers already described, is supplemented by the action of a double row of eye-brow bnrnishers, I and I, which are located between the said handle and blade bnrnishers, and mounted so as to extend transversely through two shafts J and J, respectively located on opposite sides of the series of knives, at points opposite each other. These burnishers are arranged in correspondencewith the bnrnishers already described, and burnish the eye-brows of the knives, as shown by Fig. 3 of the drawings. Eaclrof theseshafts is provided at one end with a pinion J the.

. said pinions meshing into each other, so that the two shafts turn correspondingly. The shafts are turned by a knocker J secured to one of the said pinions, and extending beyond the periphery thereof to engagewith a stop J forming a part of the machine frame A, when the shafts are lifted, as will be-described later on.

The edges of the knife handles are burnished by means ofpivotcd handle-edge burnishers K, arranged in pairs, at spring'K, being located between the 'burnishersof each pair for pressing them against the edgesof the knife-handles, as will be more fully'described at another time.

The respective rows of handle-bnrnishers G andgG, are mounted in horizontal boxes L andL", transversely ohamberedatregular distances to receive the said bnrnishers. The said boxestare attached at their-ends'to the upper ends of thearmsoftwo pairs ofvertical arms respectively located at theends of the machine. 'Each of the said pairs of arms consists ofan arm M'andcounterpart arm M", both of which are swiveled upon a short shaft M journaled in the outerend of an oscillating horizontal arm M of which there is one and also a shaft ateach end of'themachine By the oscillation of the arms M M the said pairs of arms, together with, the boxes L and, L. carri'edby tl1em,are vertically reciproeated. Each pair of armsis provided with ahori-zontal locking-lever N, which is hungby a pin 0 to alug offsettingfrom the arm Mand-notched to engagewith a pin a, carriedby the arm M, in a lug ofisetting from it. Eachpairof arms is also provided witha'horizontal guard, 0011-. sisting of a link N, pivoted to a lug offsetting from the arm M", and havingits opposite end slotted as atn, to receive a pin. n carried by the arm M in a lug offsetting therefrom. Then the locking-lever N, is lifted so as to be disengaged from the locking-pin a, the arms will fall apart by gravity, whereby the bnrnishers carried by the boxes L and L, will be separated.

In explanation of the statement just made that the arms will fall apart by gravity, attention is called to Fig. 2 of the drawings, in which it will be noted that the main portions of the said arms lie on opposite sides of a vertical plane passing through the horizontal shaft M on which they are hung, and that their upper ends are weighted by the boxes L L, so that just as soon as they are freed, they willquickly fall apart by gravity, nor will they stay in place except as held there by the locking-lever N. At this time the guard N' prevents the arms from falling too far apart. On the other hand, when the locking-lever N, is engaged with the pin "a, the arms are held up in their operating positions, in which the rows ofburnishers Gand G, are brought close together, so as to engage with the handles of'any knives that may be in the machine.

Theshafts J'and J" carrying the-eye-brow bnrnishers land I, as'before stated, are journaled at their endsinthe respective members of the'twopairs of arms just described, and partake oftheir reciprocating movement,

The respective rows H and H ,of' the burnishers are mounted in horizontal boxes 9 and O, furnished with regularly spaced transverse chambers, and: constructed with depending webs 0 o, connected withthe arms of two yokes P, located, as herein. shown, between the respectivepairs of hinged arms already described, and-mounted on the ends of a horizontal shaft P, which is journaled in theouterends'of two levers P P arranged tooscillate with the levers M M before referred to, but having greater throw. The web 0, of the box 0 is attached to the-inner army, of each of the said yokes, while the web. 0, of the boxO, is secured to the upper arms QQ of two twoarmed leversv respectively pivotedupon theouter armsp Oftl'lG two yokes, the said'arms p being shorter than the arms p-before referred to. The lower arms Q, Qof'the said two-armed l6VBIS,,aI'6 respectively arranged for engagement with cams R R, mounted upon the extreme ends ofthe shaft P", whichis furnished with a manual or-hand-lever P whereby it is rotated, to bring the drops of (the said cams under the arms Q," Q" of the said two-armed: levers, and to move the said drops. of the cams out of line with the said arms. When the drops of the cams are brought under the said arms, they will rock on their pivots, their lower ends moving'inward, andtheir upper ends moving outward, whereby the box H, is separated from the box H and space secured between them for charging or discharging the knives. But when the cams are turned to throw the said two-armed levers in the opposite direction, theboxes H- and H" are brought into position for the operation Of'lihfi burnisherscarried by them upon the knife blades. Normally the said yokes PP are supported in the upright position in which they are shown in Fig. 2 of" the drawings.

The handle-edge bnrnishers shown by Fig.

and P P are oscillated, all of the burnishers' must be moved up and down on the knives, the handles and blades wh ereof are thusburnished on both sides simultaneously. If desired, the oscillating arms may be coupled together, as indicated by Fig. 2 of the drawings, bya crank T, and a link T, but that is not essential, al-

though such a construction might be foundv convenient in timing the machine.

It is apparent that in carrying out my invention, some changes in the construction and arrangement of parts may be resorted to, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations therein as fairly fall within the spirit and scope of my invention.
